As a selective antioxidant, hydrogen supports balancing your body’s redox equilibrium. Its key roles inside the body include targeting and neutralizing harmful free radicals, as well as aiding in reducing inflammation and protecting cells from excessive apoptosis.
Your body naturally has an “antioxidant defense system” (like superoxide dismutase, or SOD for short), which can clear some free radicals on its own. But when external factors—such as staying up late, high stress, environmental pollution, or UV exposure—cause a buildup of free radicals, these harmful molecules will harm your cells and tissues via “oxidative stress.” This not only speeds up tissue and organ aging, but also raises the risk of chronic inflammation and illnesses.
That’s where our hydrogen-oxygen machine comes in. It delivers high-purity hydrogen to help you tackle these common daily stressors, reducing free radical damage at its root. By stabilizing your body’s redox balance, it leaves you feeling healthier and more at ease. Also, a 2:1 ratio of hydrogen-oxygen mixed gas is delivered. This mixed gas can reduce airway resistance, increase blood oxygen saturation, and alleviate lung inflammation, making it an important adjunctive intervention for respiratory diseases such as asthma, COPD, and COVID-19. Multiple studies have confirmed its effectiveness over oxygen therapy alone.
Most people’s lungs and respiratory systems are damaged to varying degrees after experiencing COVID-19. The hydrogen-oxygen mixed gas output by the hydrogen-oxygen machine (usually in a 2:1 ratio, which meets the physiological needs of human respiratory needs) can increase the alveolar oxygen partial pressure more efficiently than pure oxygen, promote the binding of oxygen and hemoglobin, and quickly relieve common problems after COVID-19, such as chest tightness, shortness of breath, low blood oxygen, cough, sputum, and airway sensitivity.

High-Purity Hydrogen Production

Utilizing DuPont PEM membrane electrolysis technology imported from the United States, this device precisely separates hydrogen and oxygen through a proton exchange membrane, thus eliminating impurities at the source and ensuring a stable hydrogen purity exceeding 99.99%. Hydrogen is produced solely through pure water electrolysis, eliminating the need for the addition of chemicals such as alkali. This ensures purity while minimizing the risk of secondary contamination, making it suitable for long-term inhalation applications (such as healthcare and rehabilitation support).

Three Adjustable Flow Rates

Three flow rate settings: 1400ml/min, 2800ml/min, and 4200ml/min, meeting diverse needs.
1400ml/min: The four-hole output flow rates are 467ml/min (H₂), 233ml/min (O₂), 233 ml/min(O₂), and 467ml/min (H₂). Suitable for low-dose daily maintenance for a single person, or for use by children and those with sensitive conditions.
2800ml/min: The four-hole output flow rates are 933 ml/min(H₂), 467ml/min (O₂), 467 ml/min(O₂), and 933ml/min (H₂). This is designed to meet the needs of regular adult inhalation, balancing effectiveness and energy consumption.
4200ml/min: The four-hole output flow rates are 1400 ml/min(H₂), 700ml/min (O₂), 700ml/min (O₂), and 1400ml/min (H₂). This supports simultaneous use by multiple people (e.g., with dual outputs) or when high-dose inhalation is required.
Adjustment: Switch via the touchscreen with one click. The current flow rate is displayed in real time. After adjustment, the output stabilizes within 3 seconds to prevent flow rate fluctuations that affect the user experience.

Multiple Output Modes

Four core output modes are designed for different users and scenarios:
Hydrogen-Oxygen Mixed Mode: Outputs a 2:1 hydrogen-oxygen mixture (meeting human inhalation safety standards), balancing hydrogen and oxygen replenishment needs and being suitable for people with lung diseases, breathing difficulties, sequelae of COVID-19, and for daily maintenance.
Pure Hydrogen Mode: Outputs only high-purity hydrogen, suitable for those who need separate hydrogen replenishment (such as those focusing on antioxidant needs).
Pure Oxygen Mode: Outputs only oxygen, suitable for hypoxic environments or temporary oxygen replenishment.
Dual Independent Mode: The left and right ports can be set to different modes, supporting simultaneous use by two people without interfering with each other’s parameters, making it suitable for family sharing.

Smart Touch Control

Equipped with a 7.3-inch high-definition color touchscreen, the device features a fingerprint-resistant tempered glass panel and supports wet-hand operation.
Display: Real-time display of device core status, including current flow rate, output mode, remaining time, water temperature (30-60°C), TDS water quality, and other parameters. Data is visualized (e.g., high water temperature values ​​are highlighted in red).
Operation: Simply tap an icon, making it easy for both adults and children to use.

Intelligent Safety Monitoring and Alert Functions

Five real-time monitoring systems:
TDS Water Quality Monitoring: When the incoming water’s TDS value exceeds 50ppm (indicating excessive impurities), an “Abnormal Water Quality” alert will be displayed on the screen, and gas production will be suspended. The system will need to replace the pure water before restarting.
Water Temperature Monitoring: When the water temperature exceeds 65°C during hydrogen production, dual fans will automatically activate for enhanced cooling. If the temperature does not drop below 60°C within 10 seconds, the system will shut down and an alarm will sound.
Water Pressure/Level Monitoring: In the event of water shortage, a red light will illuminate, prompting “Add Water.” If no water is added within 30 seconds, the system will automatically shut down. Excessive water pressure (>0.4MPa) will trigger the pressure relief valve, and the screen will display “Abnormal Pressure.”
Circuit Safety: Built-in overcurrent and short-circuit protection modules will shut down the system within 0.1 seconds in the event of a leakage, preventing the risk of electric shock.
Alerts: Dual audio and visual (flashing screen and red icon) ensure users are aware of any abnormalities.

Intelligent Timing

The timing function ensures precise inhalation dosage. Users can set different inhalation durations to develop a regular inhalation habit. When manual supervision is not required, the timing function prevents the device from idling, thereby reducing power consumption.
